OK.  I don't know the field so I don't know what's current.  I was taught
this stuff decades ago.

Yes of course I do.  I talk of sequences because WM does, so that he
can't go off on yet another a tangent.

And set sequences have cropped up in another guise -- as sequences of
functions where the order matters, a least superficially.  WM's textbook
gives two definitions for limits of function sequences (the two usual
ones) so however he likes to paint it, he endorses /some/ meaning for
the term "limit" when applied to sequences of sets (two, infact).  That
contradicts his claim in the head post.

OK.  I've not heard the term used like that before.  Can you say more
about what you meant further up: "unless the sequence is itself
representable as 1 set and the bounding set X"?  I did not follow that
at all, and now that I know you meant the LUB of the collection of sets,
what is the "1 set"?  I get the feeling there is something important
here.
